I'm looking at trading my YM135D for a 276D. Trouble is the 276D has turf tires and I want to put on ag tires. Trouble is these are'nt standard sized rims at least as far the pilot hole and bolt circle are concerned. For the rear I want an 8x24" rim with a 4" hole and a 7.5" bolt circle for 6 bolts. The front should be a 5x14" with a 3.5" hole and a 7" circle for 6 bolts. Any ideas would be appreciated. My best alternative may be to have some centres made for standard rims. I'm in southern Manitoba.
